Dragon Quest (Japanese: ドラゴンクエスト Hepburn: Doragon Kuesuto), published as Dragon Warrior in North America until 2005, is a series of internationally best-selling console role-playing video game (RPG) titles created by Yuji Horii and his studio, Armor Project.

The series is published by Square Enix (formerly Enix), with localized versions of later installments for the Nintendo DS (NDS) being published by Nintendo outside of Japan. With its first title published in 1986, there are currently ten main-series titles, along with numerous spin-off games. Nearly every game in the main series has either an anime or manga adaptation, or both. The series has had a significant impact on the development of console RPGs, and introduced a number of features to the genre. Installments of the series have appeared on MSX computers, Nintendo Entertainment System, Super Nintendo Entertainment System, Game Boy Color, Game Boy Advance, Nintendo DS, PlayStation, PlayStation 2 and Wii video game consoles, and several models of mobile phones. Each Dragon Quest video game soundtrack is arranged into an orchestral piece and the video game series is the first to have live-action ballet adaptations.

Dragon Quest X is the most recent game in the main series. It is a massively multiplayer online game, featuring online battles. It has been released in Japan for the Wii, Wii U, Microsoft Windows, and Nintendo 3DS. Dragon Quest Heroes: Yamiryū to Seikaiju no Shiro, a PlayStation 3 and 4 game featuring the gameplay of the Dynasty Warriors series by Koei Tecmo, will be released in Japan on February 26, 2015.
